Answer:
Part 1) Option C. Same side interior angles
Part 2) Option A. 
Part 3) Option B. 
Step-by-step explanation:
Part 1) we know that
If p and q are parallel 
then
m<3 and m<5 are consecutive interior angles or Same side interior angles
and

Part 2) we know that
 -----> by consecutive interior angles (supplementary angles)
 -----> by consecutive interior angles (supplementary angles)
we have that


so
substitute

Part 3) Find the measure of angle 5
we know that

Solve for x




substitute the value of x

 
        
                    
             
        
        
        
Answer:
x=4
Step-by-step explanation:
First you want to add 8.8 to 7.2 and get 16 because you want to get x alone 
Next divide divide 4x on both sides so 4x/4x cross out and left with just x. 16/4 =4
x=4
Hope this helps!
